I remember reading an article written partly in response to Dead Space, stating why it isn't really a horror game and what really should be present in a game to truly make it work for the horror genre. This included not having a feeling of being able to confront the enemies toe-to-toe, having resources sufficiently scarce that the player can feel the severity of their lack, etc.

I've played the demo partly, and it feels like this game really accomplishes that.

I'm pretty impressed. I might chip in the cash to buy it later when I'm ready for a new game.
